Neckera caule longissimo filiformi pendulo pinnatim 
ramoso, foliis lanceolatis acuminatis serrulatis substri-

Has. In Nepal, arboribus. Hon. D. Gardner. 
Caules e ramis arborum pendentes, longissimi, filiformes, flexu- 
osi, molles, pinnatim ramosi, ramis iterumque pinnatis, pin- 
nulis brevibus plerumque simplicibus. Folia fusco-viridia, un- 
dique imbricata, erecta, vel erecto-patentia, lanceolata, acumi- 
nata, vix concava, substriata, margine ad apicem serrata, nervo 
brevi ante medium evanescenteinstructa. Perichetialia lon- 
giora, magis angusta, flavescentia, enervia. Seta perbrevis, 
recta. Capsula oblonga, fusca. Calyptra brevis, conico-aeu- 
minata, pallide fusca, pilosa, hinc longitudinaliter fissa. Oper- 
culum conico-subulatum. Peristomii dentes ext. 16, ciliis 
flavescentibus setaceis his alternantibus. 
This plant came intermixed with Neckera filamentosa, and 
like that grows pendent from the branches and trunks of trees. 
It ranks naturally with N. heteromalla and filiformis of Hedwig, 
and I should have expected that, like them, it would have hada 
mitriform calyptra, and thus have come into the genus Daltonia. 
Such, however, does not appear to be the case.
